Description

The automatic method for controlling passing neutral section and the device thereof of electric locomotive

Technical field

The present invention relates to a kind of automatically undue phase control setup of electric locomotive, refer to a kind of automatically undue phase control setup especially based on motorcycle safety informix monitoring device TAX case (hereinafter to be referred as the TAX case).

Background technology

Electric locomotive is to obtain single phase alternating current from the electrical network that is erected at the railway side power is provided in the process of moving.Respectively alternating of electrical network three phase mains is arranged on the different highway sections, and the insulation intersection point between each phase is called the phase-splitting point, and locomotive needs to disconnect line circuit breaker by phase-splitting point the time, the impact of avoiding undue phase time power phase sudden change to cause.The driver's of the undue phase time of locomotive operating process is as follows: separates mutually when far away, and the locomotive cruising, level (corresponding to certain locomotive electric current) handle is in the normal position; Near phase-splitting point the time, the driver need move back level, arrives before the outage mark to guarantee locomotive, and a level potential energy drops to zero and disconnect line circuit breaker, make then locomotive under the situation of not power taking stream by the phase-splitting point; After phase-splitting point, closing the closed line circuit breaker in electric mark place, wait locomotive state to recover upgrading position, back.So-called outage mark refers to should disconnect before this kilometer post (being the position data) at line circuit breaker place, and close the electricity mark refer to should be after this can closed line circuit breaker place kilometer post, outage mark and close the electricity mark and be originally by identifying and indicated.Be with outage mark in the practical operation and close the operating position that the electricity mark retrained the phase-splitting operation.

Thisly rely on artificial processing ease misoperation to take place fully because of all human elements, simultaneously, crossing in the phase-splitting operation of driver, bit position separates and puts nearer mutually or locomotive speed when very fast if begin to demote, need degradation position fast, if but the degradation bit rate is too fast, and the quick variation of locomotive electric current can cause the locomotive speed sudden change, may damage locomotive equipment, also cause personnel's injury accident easily.If separate mutually far away or locomotive speed slowly the time, the driver has to finish than plenty of time and moves back a grade bit manipulation, but move back long running velocity to locomotive of level operating time adverse effect is arranged.Above process driver experience is one's very own operated, and is difficult to the control process that reaches optimum.Therefore the automatic technology of crossing phase-splitting is developed and uses.

At present, the automatic phase-splitting excessively of electrified railway locomotive both at home and abroad mainly contains 3 kinds of modes: ground switch automatic switching mode, form by equipment such as insulated overlap, jointless track circuit, vacuum load switch transformer, lightning arrester, feeder distribution centres, it is short to have the locomotive power-off time, the advantage that can adapt to multiple rate request, but system is very complicated, cost is high, the equipment maintenance cost height; The automatic power-down mode of on-pole switch is made up of equipment such as sharing shackle, vac switch, and the locomotive power-off time is short, but the undue phase time of locomotive produces overvoltage, overcurrent, and device structure is also comparatively complicated; The locomotive automatic guidance is crossed the phase-splitting mode, different with the first two kind, this mode is by disconnect main circuit breaker of railway engine before phase-splitting point, in the mode of not power taking stream by the phase-splitting point, wherein Chang Yong a kind of method is that bury a little on ground, system is by insulated overlap, ground magnet, locomotive is accepted equipment compositions such as control setup, system is simpler, but in order to provide control information to locomotive, need bury magnet in advance in each phase-splitting point both sides at railway scene, this is a huge engineering beyond doubt, in addition, though bury point mode through improving, but the running velocity to locomotive is restricted, still can't satisfy locomotive and descend the requirement of phase-splitting, and wayside inductor safeguards and be difficult for that maintenance cost is higher in friction speed.

More than three kinds of modes equipment on ground or the bar should be arranged, on locomotive, can't monitor in real time, when on ground or the bar during breakdown of equipment these equipment, device can't be crossed phase-splitting automatically, had little time when manual by the driver again, easily cause the charged serious consequence of crossing phase-splitting, so reliability has been relatively poor.

The motorcycle safety informix monitoring device TAX case (hereinafter to be referred as the TAX case) that the existing power locomotive is installed, can obtain and write down present speed, the current location of locomotive in real time (also represents with kilometer post, can be accurate to rice), information such as current station number, wherein current location is to add that by reference position range ability obtains, during by railway signal along the line, position data is revised automatically at locomotive; Each phase-splitting is put cooresponding outage mark and is closed electric mark and can detect and be stored in the computing machine; The utmost point position signal of handle can be gathered by analog-to-digital conversion module, and these data that needed when the driver carried out the phase-splitting operation can be obtained by computer real-time, and the folding of locomotive level, line circuit breaker also can be controlled by the computing machine output signal.Therefore, adopt the automatic neutral-section passing device that comprises computing machine to realize that the undue automatically control mutually of apery is to solve the automatic new way of crossing the phase-splitting problem of electric locomotive.

The specific embodiment

Automatically the too facies-controlled scheme drawing of the embodiment of the invention is a kind of automatically undue phase mode of apery that is realized by vehicle-borne automatic neutral-section passing device as shown in Figure 1.Its diagram of circuit may further comprise the steps as shown in Figure 2:

Calculate locomotive current location l and whether enter phase-splitting indication distance, step 100; If not, recirculation is judged; If, begin the automatic phase process of crossing, carry out next step;

Judge whether the cooresponding car station number of l0, step 110 are marked in next outage to current car station number; If not, finish the automatic phase process of crossing; If send phase-splitting indication signal, step 120 to driver's cab; And carry out next step;

According to the locomotive current location l, the present speed v that obtain in real time and as front hand grip level n,, judge whether locomotive enters the valid function distance of crossing phase-splitting automatically, step 130 in conjunction with next outage mark l0; If not, then recirculation is judged; If then carry out next step;

Automatic neutral-section passing device obtains the level control, level is dropped to zero, step 140; Before arriving outage mark l0, disconnect line circuit breaker, step 150 then;

Judge that whether locomotive is by closing electricity mark, step 160; If not, then recirculation is judged; If, closed line circuit breaker, step 170; And carry out next step;

After locomotive states such as time-delay a period of time recover, step 180; Level is returned to as front hand grip level n '; Then the level control is given back bar handle, step 190 is finished once the automatic control process of crossing phase-splitting.

Need to prove, above-mentioned flowcharting be to finish automatically the control of crossing phase-splitting by single-threaded mode, whether the time, this step is carried out in the master controller circulation in step 100,130 and 160 judged result.

In real-world operation, above-mentioned flow process generally is as the automatic phase-splitting subprocess of crossing, and for not the time, master controller withdraws from this subprocess earlier, when main flow is carried out this subprocess again, carries out new judgement again in the judged result of step 100; For not the time, master controller is put a mark and is represented that locomotive has entered the indication distance, withdraws from this subprocess in the judged result of step 130, when main flow is carried out this subprocess again, read this mark after, direct execution in step 130; When the judged result of step 160 for not the time, master controller is put a mark and is represented that locomotive has entered the valid function distance of crossing phase-splitting automatically, withdraw from this subprocess again, when main flow is carried out this subprocess again, read the mark that locomotive has entered the indication distance earlier, read the mark that locomotive has entered the valid function distance again, just direct execution in step 160, when the judged result of step 160 when being, above-mentioned two marks are all emptied, carry out next step again.Realize the cycle criterion process of above-mentioned steps like this.

Outage mark is very crucial with closing electric target data in undue control mutually automatically, and existing kilometer post data are because the disunity of method of calculating, and has error between the kilometer post of TAX case record.The present invention has taked in real-world operation the mode of image data to obtain above kilometer post.Its method is, when electric locomotive moves, gather the bow net voltage data of locomotive watthour meter and the kilometer post in the TAX case with computer real-time, when noting all bow net voltages and be zero, cooresponding kilometer post is put in the phase-splitting that locomotive passed through just, because the required distance that cuts off the power supply mark on the different highway sections and close between electric mark and the phase-splitting point is different, the present invention goes out cooresponding outage mark according to the disconnected distance calculation of closing requirement between electric mark and the phase-splitting point of each phase-splitting point and closes electricity and mark and be stored in the device.This method is very simple, and the data of collection are also very accurate, and error is very little.

In above step, the phase-splitting indication is not to finish the operation that phase process must carry out, and still, in the process of automatic phase-splitting excessively, error in judgement may appear in automatic neutral-section passing device, fails to carry out the normal automatic phase-splitting operation of crossing.At this moment just need the driver manually to carry out emergency operation, if but the driver when finding this problem locomotive separate too closely mutually, will have little time to handle and be difficult to avoid accident to take place.Therefore, in the present embodiment, comprised a step of carrying out the phase-splitting indication with a certain distance from the outage mark time, present embodiment judges whether locomotive enters phase-splitting and indicate that the method for distance is: calculate locomotive current location and next outage mark l ₀Between distance whether smaller or equal to phase-splitting indication distance, delta l ₁, at locomotive apart from outage target distance less than Δ l ₁The time, send indication signalisation driver.Δ l ₁Value is by default, and it should when guaranteeing that the driver finds automatic neutral-section passing device work mal, have ample time and manually finish the phase-splitting operation greater than the valid function distance, and the accident that prevents takes place.Can certainly in device, store the kilometer post of the corresponding indication point of each phase-splitting point, directly compare with locomotive current location and this kilometer post.

But, different locomotive routings identical kilometer post may occur sometimes on different highway sections, be that automatic neutral-section passing device can collect identical current location, and compare calculating with next outage target relevant position, there is the phase-splitting point on the highway section and in fact have only, will produces misoperation like this.The present invention is in order to be applicable to various situations, in advance the cooresponding station number of each outage mark is stored in the system, after the distance between locomotive current location and the outage mark is smaller or equal to phase-splitting indication distance, to compare from current car station number and the cooresponding car station number of this outage mark that the TAX case obtains, if both are identical, just send the indication signal, otherwise finish the automatic phase process of crossing.When promptly having only two factors of distance and car station number to satisfy simultaneously, just carry out the phase-splitting indication.

So-called valid function distance refers to when this distance begins to operate, can guarantee under present speed locomotive can be reposefully from the initial level potential drop to zero, and before next outage mark the disconnection line circuit breaker.Putting before this, the delay time that falls the one-level level can not be excessive, in order to avoid locomotive running speed affects adversely, the valid function distance that the present invention carried not is a fixed numbers, but relevant with the speed and the current level of locomotive operation.

Guaranteeing that locomotive operation is steady, can be zero up to level with locomotive from the current level n decline of delaying time step by step.In addition, for certain conservative factor is provided, require locomotive also having one to insure distance, delta l apart between the outage mark ₂The time, level just drops to zero and disconnects line circuit breaker, as Δ l ₂Desirable 50 meters.When adopting this degradation position mode, calculate the valid function distance in the following manner:

Set a maximum delay time Δ t that can guarantee the steady degradation step by step of locomotive position earlier _MaxAccording to current location l (by obtaining the kilometer post at locomotive real time position place), present speed v (obtaining), current level n (obtaining) and outage mark l by real-time collection by real-time communication with the TAX case with the real-time communication of TAX case ₀(being stored in the system in advance), calculate with the present speed operation arrive outage timestamp level serve as zero one-level level bit time Δ t falls.Concrete computing formula is as follows:

$\mathrm{\Δt}=\frac{|l-l_0|-\mathrm{\Δ}{l}_2}{\mathrm{nv}}\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\left(1\right)$

Then with Δ t and Δ t _MaxCompare.If Δ t＞Δ t _Max, then locomotive does not enter the valid function distance; If Δ t≤Δ t _Max, then locomotive has entered the valid function distance, and the Δ t that we obtain this moment is designated as Δ t ₀

But,, promptly equal the upper class level n of the corresponding level of present speed when the level that is dropped to during than the only big one-level of the cooresponding level of locomotive present speed ₁The time, after a time-delay, directly the locomotive level is dropped to zero (seeing the vertical descent stage of level curve among Fig. 1), compare up to zero with the position of demoting step by step, can't produce extra impact to locomotive operation.Because after the locomotive level is less than the pairing level of locomotive present speed, locomotive does not rely on tractive force but relies on inertia to advance.For instance, suppose that locomotive is divided into 1-15 level, each is corresponding to the running velocity of 10-150km/h, and every liter of one-level corresponding speed increases 10km/h, and the locomotive present speed is 108km/h, round downwards divided by 10 with 108 that to obtain cooresponding level be 10 grades, the current level of locomotive is 15 grades, then in the process of automatic phase-splitting excessively, only needs the locomotive level is reduced to 11 grades step by step, after this just can directly the locomotive level be reduced to zero through a time-delay again, disconnect line circuit breaker again.By closing in the upgrading position process after electricity is marked, also level directly can be risen to the pairing level n of locomotive present speed ₁', be example also with top example, suppose that the speed by phase-splitting point back locomotive is 98km/h, cooresponding level is 9 grades, just can directly the locomotive level be risen to 10 grades from above freezing, and then rise to current handle level step by step, so just can shorten the automatic time that crosses phase process of locomotive, thereby improve the running velocity of locomotive, what the embodiment of the invention was taked is exactly the method for this lifting level.

When taking this mode, judge whether to enter valid function apart from the time, judge at first whether current level n is less than or equal to the upper class level n of the corresponding level of present speed ₁

If n≤n ₁, then relatively l is marked in current location l and outage ₀Between distance whether smaller or equal to insurance distance, delta l ₂, if then locomotive enters the valid function distance; If not, then locomotive does not enter the valid function distance.

If n＞n ₁, then judge by following formula whether locomotive enters the valid function distance:

$\mathrm{\Δt}-\frac{|l-l_0|-{\mathrm{\Δl}}_2}{(n-n_1)v}\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\·\left(2\right)$

Δ t still represents the operation with present speed v, at the insurance distance, delta l of distance outage mark one setting ₂The time level be zero one-level level bit time Δ t, n fall ₁Represent the upper class level of the corresponding level of present speed, the same formula of other meaning of parameters (1).Then with Δ t and Δ t _MaxCompare.If Δ t＞Δ t _Max, locomotive does not enter the valid function distance; If Δ t≤Δ t _Max, locomotive has entered the valid function distance.We are designated as Δ t with Δ t at this moment ₀

If do not take the step of phase-splitting indication in the undue control mutually, then current car station number and next phase-splitting are put the comparison of corresponding car station number and can be carried out after locomotive enters the valid function distance again, if both are identical, carry out follow-up control too mutually again, if different, then withdrawed from the phase-splitting automated procedure.

After locomotive entered the valid function distance, passing phase insulator device obtained the level control, as n＞n ₁The time, export current level n earlier, time-delay Δ t ₀After current level n is reduced to n-1, drop to n then step by step ₁, through a time-delay level is dropped to zero again; As n≤n ₁The time, then level is directly dropped to zero.As n＞n ₁The time fall one-level level delay time Δ t and can calculate according to formula (2), l wherein, the v value is obtained from the TAX case in real time, can obtain cooresponding Δ t, fall the one-level level after time again through this Δ t and get final product, can reach like this before the outage mark and level to be dropped to zero and disconnect the controlled target of line circuit breaker.

Also can directly adopt the Δ t that obtains in the valid function distance calculation ₀Value, as the fixing one-level level delay time that falls, as shown in Figure 1 be this method.Lack (generally being no more than one minute) because cross phase process, locomotive speed changes little, Δ t value that each level place calculates in real time and Δ t ₀Value difference is not very little.Use Δ t ₀Value also can reliably guarantee the realization of controlled target as the fixing one-level level delay time that falls, and has simplified algorithm simultaneously.

Locomotive by phase-splitting point after, if undue phase control setup comparison current location and close the electricity mark is by closing electric mark place, then control the line circuit breaker closure, time-delay a period of time, treat that the locomotive recovering state can horsepower output after, the locomotive level is directly risen to the cooresponding upper class level of present speed n from the zero level position ₁', and then rise to step by step as front hand grip level n ', because the mandatory controlled target during the degradation position, the delay time of upgrading position does not have the strict time requirement, as long as keep locomotive steady, every delay a period of time rises the one-level level and gets final product.Obtain in the process of level control at automatic neutral-section passing device, the operation of bar handle is invalid, but the driver still can the regulating handle position, and therefore undue handle level n before and after mutually might not be identical with n '.

Automatically undue phase control setup of the present invention as shown in Figure 3.Mainly comprise master controller 11, and hold display box 21 etc. with master controller 11 bonded assembly shift position control module 13, communication interface 15, line circuit breaker control module 17, A end display box 19, B.Automatically undue phase control flow shown in Figure 2 is by 11 programmings realize to master controller.

Fig. 4 is the minimum system structural representation of master controller 11, comprises CPU 111, address latch 112, program store 113, data memory 114, data logging memory device 115, crystal oscillator clock circuit 116, Power Supply Monitoring and reset circuit 117, address decoder 118.The host CPU 111 of present embodiment adopts 16 micro controller system TN80C196KB.Address latch 112 adopts 74LS573.Program store 113 uses 27256.Data memory 114 adopts 6264.Data logging memory device 115 adopts FLASHRAM.The electricity mark is marked, is closed in the outage of each phase-splitting spot correlation and the car station number is stored in the program store 113; Data such as the position when the data logging memory device is then noted train number, driver, locomotive operation, speed, level variation.Need to prove that foregoing circuit is a specific embodiment, also can realize controllable function of the present invention with other circuit.

Power Supply Monitoring among Fig. 4 and reset circuit 117 adopt the DS1232 chip, its VCC pin power connection, and the RESET-pin connects the RESET pin of CPU 111, and STROBE connects the P2.5 pin of CPU 111.The VCC pin of DS1232 is the input pin of power supply, simultaneously also is that power supply detects pin, and when VCC≤4.75V, DS1232 will constantly reset CPU 111 by the RESET-pin, thereby plays the effect of power supply detection.When normal operation, CPU 111 is every regular time (being 1.6s to the maximum), will be once with the STROBE pin saltus step of DS1232, be equivalent to watchdog timer constantly clear " 0 ", mode of operation with notice DS1232 main frame is normal, if do not have saltus step at specific time, then DS1232 will send the RESET-pulse, CPU 111 is resetted, until its normal operation.Like this, if main frame is in case crash, DS1232 will allow its hot reset, makes it recover normal working.Thereby improve the reliability of system works.

The two ends of electric locomotive (hereinafter referred to as side a and b) all have driver's cab, the driver may operate by any end therein, automatic neutral-section passing device of the present invention is in order to satisfy this requirement, its shift position control module 13 is by end position signal relay J1 and normally closed contact J1-1 and J1-3, open contact J1-2 and J1-4, level control transformation K switch 1, the A/D change-over circuit, and the D/A change-over circuit is formed.The end of contact J1-1 to J1-4 is connected with A end bar handle, B end bar handle, A terminal car level control circuit, B terminal car level control circuit respectively; Level control transformation K switch 1 has manually, input end and a mouth automatically, manually input end links to each other with the other end of A/D change-over circuit and contact J1-1, J1-2, automatically input end links to each other with the D/A change-over circuit, and mouth links to each other with the other end of contact J1-3, J1-4.Level control transformation K switch 1 wherein can be by relay the combination of normally-open normally-close contact realize that master controller 11 can be realized the switching of level control by controlling this relay.If locomotive only needs at single end control,, directly with bar handle with locomotive level control circuit link to each other just passable with mouth the manual input end of level control transformation K switch 1 as long as remove end position signal relay J1 and contact thereof.

When locomotive normally moves, the mouth of level control transformation K switch 1 and manually input end connection.If the driver is in the operation of A end, make the end position signal relay J1 must not electricity (can control) by button switch, contact J1-1 and J1-3 closure, J1-2 and J1-4 disconnect, the A/D change-over circuit is gathered A end bar handle level place value in real time, import master controller 11 after being converted to digital signal, export the level control signal to A terminal car level control circuit by A end bar handle; If the driver is in the operation of B end, it is electric that end position signal relay J1 is got, and contact J1-1 and J1-3 disconnect, J1-2 and J1-4 closure, the A/D change-over circuit is gathered B end bar handle level place value in real time, exports the level control signal by B end bar handle to B terminal car level control circuit.

Undue phase time, the level changeover control signal of master controller 11 outputs is connected the mouth of this K switch 1 of control and automatic input end, and this moment, master controller 11 obtained the level control.The A/D change-over circuit still can be gathered A end or B end bar handle level place value in real time, and the level control signal of master controller output is after the D/A change-over circuit is transformed to digital signal, export to A terminal car level control circuit (when the driver in A when operation end), or B terminal car level control circuit (as driver during) in the operation of B end.

A/D change-over circuit in the present embodiment adopts the AD202 chip that has isolation and amplification simultaneously, the D/A change-over circuit is made up of AD558 and AD620, AD558 is in 0～1.5V scope internal linear degree the best, therefore the level control signal of master controller 11 outputs is earlier by AD558 D/A conversion in this scope, export locomotive level control circuit to after amplifying 10 times by AD620 again, improve the level control accuracy.

Communication interface 15 adopts to have long distance and drives and strong isolation 485 serial communication interfaces of interference protection ability, and CPU11 can receive present speed, time, the position of TAX case in real time by this interface, and information such as train number, department's plane No..

Because in the line circuit breaker is heavy current, the employing two-step relay between master controller 11 and the line circuit breaker is controlled, and wherein the control voltage of one-level relay is 5V, and the control voltage of secondary relay is 110V.As shown in Figure 3, line circuit breaker control module 17 is made up of two groups of secondary relays.The line circuit breaker that the one-level relay J 11 of first group relay is accepted master controller 11 outputs disconnects control signal, and secondary relay J 12 is controlled by the output signal of one-level relay J 11, and it outputs signal to line circuit breaker tripping operation control circuit; The one-level relay J 21 of second group relay is accepted the closed control signal of line circuit breaker of master controller 11 outputs, and the secondary relay is controlled by the output signal of J22 one-level relay J 21, and it outputs signal to the line circuit breaker contacting controling circuit; Master controller 11 disconnects with this or closed line circuit breaker.To or cut-off status signal from collect closed of line circuit breaker secondary contact simultaneously and feed back to master controller 11.

A end display box 19 and B end display box 21 are separately positioned in the driver's cab at locomotive two ends, link to each other with master controller 11 by shielded cable, the panel of box is provided with six status indicator lamps, is respectively applied for states such as indicating device is normal, plant failure, phase-splitting indication excessively, level control (referring to that level is by CPU or bar handle control), line circuit breaker disconnection, line circuit breaker closure.In addition, the rattler that fault alarm is used is housed also in the display box, makes this device have sound and light of alarm.By the setting of display box, the driver can in time understand the automatic situation of crossing phase-splitting of device and locomotive, guarantees too facies-controlledly to finish smoothly.For example, when CPU 111 detects fault, display box in the driver's cab can send sound and light alarm, the driver can be with the device release, change and carry out manually operated by the driver and cross phase-splitting operation, if the driver finds passing phase insulator device and does not normally carry out the phase-splitting indication that the phase-splitting of crossing that also can in time meet an urgent need is operated, and makes this device possess the fault prognosis function.

More than describe the automatic neutral-section passing device of the embodiment of the invention in detail, for program work more reasonable, in the specific algorithm, consider that the driver may manually participate in, between step 100, can increase the whether step of release of a judgment means, if withdrawed from and cross phase process automatically, if not, carry out next step; Herein, also can before step 130 and step 150, increase by one respectively and judge whether open circuited step of line circuit breaker, if, then leap to step 160, if not, then order is carried out subsequent step.

Automatic phase-splitting excessively shown in Figure 5 and electric weight dump device can be realized the function of the collection phase-splitting point kilometer post described in the control method of the present invention.Except that in the module of above-mentioned automatic neutral-section passing device, this device also comprises the communication change-over swith K2 that is switched by master controller 11 controls, and and master controller 11 bonded assembly IC-card interface circuit 41 and data wireless transceiver modules 43, wherein communication change-over swith K2 have the first input end that links to each other with the TAX case, with locomotive intelligent electric meter bonded assembly second input end, and one and communication interface 15 bonded assembly mouths.Master controller and TAX case, intelligent kilowatt-hour meter and be digital signal with ground-surface wireless telecommunications receive.

The locomotive intelligent electric meter can accurately measure the information about power of locomotive.Master controller 11 by with this intelligent electric meter communication, can read and write down bow net voltage in real time.When device is gathered phase-splitting point kilometer post at the locomotive real-world operation, automatically control is not worked too mutually, master controller 11 is by control communication change-over swith K2 soon through phase-splitting point the time, read the bow net magnitude of voltage in real time with the intelligent electric meter communication, when the bow net voltage that reads is zero, master controller 11 switches communication change-over swith K2, and the kilometer post that reads from the TAX case is exactly the kilometer post numerical value of this phase-splitting point at once.

Intelligent electric meter is except bow net voltage, can also recording frequency, electric current, forward is meritorious, forward is idle, reverse meritorious, reverse idle or the like information about power, the bow net change of voltage curve that but independent ammeter can not binding time, location information writes down locomotive, frequency variation curve, electricity for locomotive electric current change curve can not be realized timesharing, section metering and the clearing of electric locomotive energy consumption.Automatic phase-splitting excessively of the present invention and electric weight dump device then can be realized these functions.The master controller 11 of this device (as 1s) at set intervals switches communication change-over swith K2 once, by communication interface 15 alternative expression ground and intelligent electric meter and the communication of TAX case, when information such as the time in the TAX case, position, speed satisfy the record condition of setting, when perhaps the information about power of intelligent electric meter satisfies the record condition of setting, send interrupt signal to master controller 11, master controller 11 is judged back, the interrupt signal place of sending from wherein reading corresponding data and storing into the data logging memory device 115.Record condition can be set as required, as kilometer post can 1 kilometer record of every variation once, forward is meritorious, forward is idle, oppositely meritorious, oppositely idle can be zero by reaching specific time, speed, change condition record such as station.Electric quantity data passage period, kilometer post is in addition related, just can realize the requirement of electric energy timesharing, section metering.

Certainly, in the locomotive normal course of operation, cross phase process automatically, just must keep in communication with the TAX case always, after finishing phase process, recover the mode of communication in turn again if entered.

These data can be dumped to the ground-based computer system by IC-card interface circuit 41, IC-card is inserted dump socket data download on the device panel, utilize corresponding process software that the data of record are analyzed, just can obtain energy consumption in time or the change curve of position, realize the section metering and the clearing of electric energy.In order to exchange with ground more easily, also set up a data radio receiving transmitting module 43 on the device, when going back to the storehouse, locomotive data are sent to the ground-based computer system with wireless mode.

By information, can also obtain bow net change of voltage curve, frequency variation curve, electric current change curve, level change curve etc. in conjunction with TAX case, intelligent electric meter and bar handle level.In addition, with the associating informations such as department's plane No., train number, engine number of storage in information about power and the device, can realize easily to electric weight the branch people, divide the statistics of car, timesharing.

If the communication change-over swith K2 among Fig. 5 is cancelled, be connected with the TAX case with intelligent electric meter respectively and use two communication interfaces instead, the switching that just can end the dependence upon change-over swith comes communication in turn, need only rely on program loop visit intelligent electric meter and TAX case, accept interrupt signal, and cross other request of refusal response in the phase process automatic, can realize the automatic function of crossing phase-splitting and electric quantity metering dump device in the embodiment of the invention equally.

If merely in order to realize the time sharing segment metering and the dump function of electric weight, the device that uses master controller 11, communication interface 15, communication change-over swith K2, IC-card interface circuit 41 or data wireless transceiver module 43 to form, perhaps use master controller, the device of two communication interfaces, IC-card interface circuit or data wireless transceiver module compositions gets final product.

Therefore, protection scope of the present invention should be as the criterion with claim, and the equivalent variations that technical solution of the present invention is done should belong within protection scope of the present invention.
